Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA PREPARAR GRANULOS A PARTIR DE MATERIALES LIQUIDOS ADECUADOS, PARTICULARMENTE PARA PRODUCIR FERTILIZANTES SOLIDOS. CONSISTE EN HACER QUE CREZCAN NUCLEOS SOLIDOS, EN UN LECHO QUE SE MANTIENE FLUIDIZADO POR UN GAS QUE FLUYE ASCENDENTEMENTE, HACIENDO QUE UN MATERIAL LIQUIDO SOLIDIFIQUE LOS NUCLEOS Y SEPARAR LOS GRANOS ASI OBTENIDOS DEL LECHO, EN DONDE EL MATERIAL LIQUIDO SE INTRODUCE EN EL LECHO DE NUCLEOS FLUIDIZADO, DESDE EL FONDO HACIA ARRIBA CON LA AYUDA DE UN DISPOSITIVO ALIMENTADOR. EL DISPOSITIVO SE COMPONE DE: UN CANAL CENTRAL (1), QUE EN UN EXTREMO CONECTA CON UNA LINEA DE LIQUIDO Y EN EL OTRO EXTREMO DIRIGE HACIA LA CAMARA DE ROTACION (3).
